Menorrhagia in adolescents with inherited bleeding disorders

STUDY OBJECTIVES

We reviewed the management and treatment outcomes of menorrhagia in adolescents with inherited bleeding disorders and assessed the impact of menorrhagia on their quality of life.

DESIGN

Retrospective review of case notes and a questionnaire study.

SETTING

Comprehensive-care hemophilia treatment center.

PARTICIPANTS

Adolescents with inherited bleeding disorders who had registered at the center and were attending the multidisciplinary hemophilia and gynecology clinic for management of menorrhagia.

INTERVENTIONS

Review of medical records and assessment of menstrual blood loss using the pictorial blood assessment chart and quality of life measurements during menstruation using a questionnaire.

MAIN OUTCOME MEASURES

Scores on pictorial blood assessment charts and quality of life measurements before and after treatment.

RESULTS

Of 153 girls aged 12 to 19 years who had registered at the center and had an inherited bleeding disorder, 42 (27%) attended the multidisciplinary clinic for management of menorrhagia. The majority (38/42; 90%) had experienced menorrhagia since menarche. Of the group, 5 (12%) required hospital admission for acute menorrhagia and severe anemia. Treatment options for menorrhagia included tranexamic acid, desmopressin, combined oral contraceptive pills, clotting factor concentrate, and the levonorgestrel intrauterine system. These treatment modalities, alone or in combination, were associated with a reduction in menstrual blood loss (median pre- and posttreatment pictorial blood assessment chart scores were 215 and 88, respectively) and improvement in quality of life scores (median pre- and posttreatment were 26 and 44, respectively).

CONCLUSIONS

Menorrhagia is a common symptom in adolescents with inherited bleeding disorders. It can present acutely, and it adversely affects quality of life. Treatment options include hemostatic and/or hormonal therapies and can improve the quality of life of affected girls.

Puerperal loss (lochia) in women with or without inherited bleeding disorders

OBJECTIVE

To assess the quantity and duration of lochia in women with or without inherited bleeding disorders and to identify factors that influence lochial loss.

STUDY DESIGN

Pictorial blood assessment chart was completed by 115 pregnant women (21 with or carriers of inherited bleeding disorder and 94 without bleeding disorder) using standardized sanitary products.

RESULTS

The median duration of lochia was significantly longer in women with (or carriers of) inherited bleeding disorder (39 days; range 21-58) compared with women without bleeding disorder (31 days; range, 10-62; P = .03); however, the median lochial loss were similar (441 mL; range, 135-1290 vs 429 mL; range, 112-1295; P = .59). Long labor and instrumental delivery were associated with heavier lochia.

CONCLUSION

Pictorial blood assessment chart is potentially a useful tool in the assessment of lochia. Women with inherited bleeding disorders experience longer period of lochia compared with women without bleeding disorder. Labor duration and mode of delivery influence lochial loss.

The impact of menstrual disorders on quality of life in women with inherited bleeding disorders

SUMMARY

Menorrhagia, heavy menstrual bleeding, is a common condition that has a substantial impact on the lives of many women. The objective measurement of menorrhagia is often impractical; therefore diagnosis and treatment are usually based on the direct perception of the woman. Menstrual problems are likely to be worse in women with bleeding disorders, as they are more likely to have heavy and painful menstrual periods and ovulation bleeding and pain. These can have a major impact on the quality of women's lives, especially those who suffer heavy menstruation. These problems can also lead to limitations at work and school and hinder educational and academic achievements. Only few studies describe how quality of life (QOL) changes in women with an underlying haemostatic defect; poorer QOL being associated with more frequent bleeding symptoms. Early recognition, accurate diagnosis and appropriate management of bleeding disorders should improve not only the quality of care for affected women but also their QOL. Increased awareness of the high prevalence of menstrual problems especially menorrhagia is essential for early diagnosis and provision of appropriate treatments without any delay. Accurate knowledge of the impact of menorrhagia on health-related quality of life (HRQOL) and its adequate assessment help individualize treatment and assess the magnitude of changes in HRQOL. An ideal situation would be to use a generic and a disease-specific measure together so that comparisons can be made on a general and disease-specific level.

Bernard Soulier syndrome in pregnancy: a systematic review

Bernard Soulier syndrome (BSS) is a rare disorder of platelets, inherited mainly as an autosomal recessive trait. It is characterised by qualitative and quantitative defects of the platelet membrane glycoprotein (GP) Ib-IX-V complex. The main clinical characteristics are thrombocytopenia, prolonged bleeding time and the presence of giant platelets. Data on the clinical course and outcome of pregnancy in women with Bernard Soulier syndrome is scattered in individual case reports. In this paper, we performed a systematic review of literature and identified 16 relevant articles; all case reports that included 30 pregnancies among 18 women. Primary postpartum haemorrhage was reported in 10 (33%) and secondary in 12 (40%) of pregnancies, requiring blood transfusion in 15 pregnancies. Two women had an emergency obstetric hysterectomy. Alloimmune thrombocytopenia was reported in 6 neonates, with one intrauterine death and one neonatal death. Bernard Soulier syndrome in pregnancy is associated with a high risk of serious bleeding for the mother and the neonate. A multidisciplinary team approach and individualised management plan for such women are required to minimise these risks. An international registry is recommended to obtain further knowledge in managing women with this rare disorder.

Outpatient medical management of missed miscarriage using misoprostol

We wanted to evaluate the efficacy, safety and acceptability of misoprostol for outpatient management of missed miscarriage. This was a prospective observational study conducted in the early pregnancy unit of a university teaching hospital involving women attending the unit with a diagnosis of missed miscarriage. All women with a missed miscarriage of <12 weeks' gestation and opting to have medical management were eligible for inclusion. Women who consented to take part were given 800 microg of misoprostol in the unit and advised to take two further doses of 400 microg of misoprostol, orally, 3 h apart, the following day at home. Outcome measures included success rates, emergency admission rates, blood transfusion rates, pain scores, satisfaction scores, incidence rates of side-effects and number of women who would choose medical management in future. Of the 268 women diagnosed as having a missed miscarriage during the study period, 75 (28.0%) opted to have medical management. Over three-quarters (n = 58, 77.3%, 95% confidence interval (CI) 66.2 - 86.2) of the women achieved successful complete medical evacuation. Overall, five (6.7%; 95% CI 2.2 - 14.8) women presented for emergency admission. The mean visual analogue scale (VAS) score of all women was 6.7 (SD = 2.8) and the mean satisfaction score was 8.6 (SD = 2.1). Two-thirds of women (n = 50, 66.7%) said that they would choose to have medical evacuation in a future miscarriage, while seven (9.3%) were unsure. A total of 70 (93.3%) women said they preferred to have the treatment at home rather than in the hospital. We conclude that medical evacuation of missed miscarriage is efficacious, safe and acceptable in the outpatient setting.

Second trimester maternal serum biochemical screening for Down's syndrome: experience of a single obstetric unit

The objective of this study was to assess the effects of mid-trimester biochemical screening on the prenatal diagnosis of Down's syndrome. All patients booked for antenatal care at the Royal Free Hospital are offered a double marker biochemical screening test (alpha-fetoprotein and free beta human chorionic gonadotrophin). The results of double marker screening tests and the notes of all cases of trisomy 21 from 1 April 1993 to 31 March 1995 were reviewed. Of the 6170 women booked in the antenatal clinic during this 2-year period 4427 (71.8%) took up the offer of biochemical screening. Four hundred and twenty-nine (9.7% of those screened) were reported positive and 293 karyotypes were performed in this group (68.3% uptake) and 253 karyotypes were also performed for other indications. Thirteen of 21 affected pregnancies had biochemical screening. The detection rate of biochemical screening in women aged <37 years was 0% (0/2) with a 8.4% false positive rate. In women aged 37 years the detection rate was 100% (11/11) with a false positive rate of 23%. The overall detection rate for Down's syndrome was 84.6% and the false positive rate was 9.5%. In conclusion, biochemical screening successfully targeted affected pregnancies in women aged 37 years and was useful in reducing the fetal karyotyping rate. However, it was disappointing in the prenatal diagnosis of trisomy 21 in women <37 years old.

Obstetric analgesia and anaesthesia in women with inherited bleeding disorders

A retrospective review was carried out on the methods of obstetric analgesia/anesthesia used in 80 pregnancies amongst 63 women with inherited bleeding disorders (19 factor XI deficiency, 16 carriers of haemophilia, 15 von Willebrand disease, seven platelet function disorders, four factor VII deficiency, one factor VII and XI deficiency and one factor X deficiency). In 72 pregnancies, the woman was seen antenatally in a multidisciplinary clinic to discuss and plan pain relief options. Regional block was performed for 41 pregnancies. The mothers were known to have a bleeding disorder in 35 of these pregnancies. Prophylactic cover was given in 10 pregnancies prior to the insertion of regional block but not required in the remaining 25 pregnancies because the coagulation defects had spontaneously normalised at term. There were six reported adverse effects from regional block similar to that found in the general population: inadequate anesthesia/analgesia (2), bloody tap (2), hypotension and a possible dural puncture which was treated conservatively. There were no reports of long-term complications. The findings show that it is possible to offer women with inherited bleeding disorders the option of regional block provided their coagulation defects have normalised, either spontaneously during pregnancy or following adequate haemostatic cover.

Menstrual problems in university students: an electronic mail survey

OBJECTIVE

To establish the prevalence of menstrual-related problems among university students.

MATERIALS AND METHODS

A questionnaire regarding gynecological, bleeding and family history was sent by electronic mail (e-mail) to all female students attending University College London (UCL).

RESULTS

A total of 767 students aged 18-39 years replied; 71% had a regular menstrual cycle. One in three (n = 264) had received some treatment for their menstrual periods (such as the combined oral contraceptive pill or simple analgesia). Those with heavy or painful periods were more likely to feel that their menstrual problems had a substantial impact on their academic and social life; however, even among those with light periods, one in every four females felt that their life was considerably affected.

CONCLUSION

A considerable prevalence of menstrual-related problems was demonstrated among this young healthy population. Additionally, the use of e-mail could present potential benefits as a research medium for this kind of study.

Review of quality of life: menorrhagia in women with or without inherited bleeding disorders

The objectives of this study were to identify the impact of menorrhagia on the health-related quality of life (HRQOL) of women in general and those with inherited bleeding disorders and to identify the commonly used tools in assessing quality of life. A review of studies evaluating quality of life in women suffering from menorrhagia was conducted. Data sources used included electronic databases Medline and Embase. Reference lists and bibliographies of the relevant papers and books were hand-searched for additional studies. Eighteen of the 53 studies identified measured quality of life prior to treatment of menorrhagia. Ten of the studies used a validated measure of quality of life. Five studies involving a total of 1171 women with menorrhagia in general and using SF-36 were considered for further review. The mean SF-36 scores in women with menorrhagia were worse in all the eight scales when compared with normative scores from a general population of women. Three studies, involving 187 women, assessed the quality of life in women with menorrhagia and inherited bleeding disorders. None of these studies used a validated HRQOL score making it difficult for comparison. However, all reported poorer scores in study women compared to the controls. In conclusion, HRQOL is adversely affected in women with menorrhagia in general and in those with inherited bleeding disorders. HRQOL evaluation is useful in the management of women with menorrhagia for assessment of treatment efficacy.

Pregnancy in carriers of haemophilia

The aim of the study was to review the complications, management and outcome of pregnancy in carriers of haemophilia over a 10-year period following the introduction of a multidisciplinary management guideline. Comparison was made to a 10-year cohort prior to implementation of the guidelines. A retrospective review of case notes of carriers of haemophilia (41 haemophilia A, 12 haemophilia B) who had received obstetric care at the Royal Free Hospital between 1995 and 2005 was conducted. There were 90 pregnancies (65 live births, 13 miscarriages, 12 terminations). Prenatal testing was taken up in 97% (63/65) of pregnancies where the mother was known to be a carrier of haemophilia. The majority (71%; 46/65) chose only to have non-invasive fetal sex determination. Seventeen (26%) had invasive testing (13 primarily for haemophilia and four primarily for chromosomal abnormalities). Termination of pregnancy was opted for in 67% (6/9) of pregnancies affected with haemophilia. Pregnancy was accompanied by a marked rise in factor VIII levels compared to only a small rise in factor IX levels. Invasive intrapartum monitoring techniques and instrumental deliveries were avoided in all pregnancies known to be at risk of haemophilia. Regional block was performed in 25 pregnancies for labour/delivery with no complications. The caesarean section rate was 47%. The incidence of primary and secondary postpartum haemorrhage was 19% and 2%, respectively. There were two neonatal head bleeding complications associated with prolonged labour or instrumental delivery. Availability of management guideline and care provided in a multidisciplinary approach can help to minimize bleeding complications in carriers of haemophilia and their newborns.

Menorrhagia associated with laboratory abnormalities of hemostasis: epidemiological, diagnostic and therapeutic aspects

Historically, the pathogenesis of menorrhagia has focused on anatomic and hormonal etiologies. However, in the past decade, numerous epidemiological studies have confirmed an association of von Willebrand factor (VWF) deficiency and menorrhagia with an incidence of VWF deficiency of 13% (95% CI, 11%, 16%). Such patients have a reduced quality of life and incur a high rate of seemingly unnecessary gynecological interventions. In addition, it appears that platelet function abnormalities are c. 3- to 4-fold more common than VWF deficiency in association with menorrhagia. The management of menorrhagia with an underlying disorder of hemostasis involves consideration of the patient's age, childbearing status and preference in terms of several options: hemostatic (oral tranexamic acid, intranasal desmopressin), hormonal (oral contraceptive, levonorgestrel intrauterine system) and surgical (endometrial ablation, hysterectomy). Pending ongoing comparative trials in bleeding disorder-related menorrhagia of intranasal desmopressin (DDAVP), tranexamic acid and further study of the levonorgestrel intrauterine device, specific recommendations cannot be made at present regarding whether one intervention is superior to the other. It should also be noted that the dose and schedule and combination of intranasal DDAVP and tranexamic acid have not been well established and warrant further study. It is imperative to establish algorithms of effective menorrhagia interventions in order to justify widespread hemostasis screening of the menorrhagia patient.

Levonorgestrel intrauterine system: bleeding disorders and anticoagulant therapy

Hemostatic disorders in women are frequently associated with long-standing menorrhagia. This leads to significant morbidity and adversely affects quality of life. Management of these women poses a particular challenge; medical treatments may be contraindicated, and surgery carries additional risks. The levonorgestrel intrauterine system (LNG-IUS) has been shown to be highly efficacy in reducing menstrual blood loss in women with normal coagulation. It is also a reliable and reversible contraceptive. Data on the use of this system in women with bleeding disorders or those receiving anticoagulant therapy are limited. Analysis of data from four reported studies suggests that LNG-IUS is a viable and safe option for the management of menorrhagia in these women. Whether the underlying hemostatic disorders lead to a shorter duration of action or prolonged irregular bleeding/spotting post insertion is unknown and requires large prospective studies. Proper counselling remains crucial for patients' satisfaction.

Screening for factor XI deficiency amongst pregnant women of Ashkenazi Jewish origin

A pilot study was conducted over a 6-month period to evaluate antenatal screening for factor XI (FXI) deficiency amongst Ashkenazi Jewish women booking for their pregnancy in a single obstetric unit. Fifty-four women of Ashkenazi Jewish origin were recruited during their visit for the routine first trimester ultrasound scan. They completed a questionnaire about their personal bleeding symptoms and had blood taken for FXI levels (FXI:C). Seven (13%) women had partial FXI deficiency. Five (9%) were newly diagnosed, and in the remaining two, the diagnosis was known previously. One infant with severe FXI deficiency was identified as a result of maternal testing. This study has shown that FXI deficiency is common amongst women of Ashkenazi Jewish origin and supports its antenatal screening in this population. However, further studies are required to evaluate its cost-effectiveness and the effect on pregnancy outcome.

Is primary postpartum haemorrhage a good predictor of inherited bleeding disorders?

A study was conducted to evaluate the value of screening for inherited bleeding disorders in women with primary postpartum haemorrhage (PPH). Over a 2-year period, women identified to have PPH (defined as >500 mL blood loss for spontaneous vaginal delivery, >700 mL for instrumental deliveries and >1000 mL for caesarean sections within 24 h of delivery) were invited to participate in this study testing for a possible underlying bleeding disorder at 3-9 months post-delivery. Women known to have an inherited bleeding disorder were excluded. Of the 5744 deliveries in our unit during the study period, 152 (3%) fulfilled the criteria for primary PPH and 50 women agreed to participate in the study. Of these, 25 (50%) had a spontaneous vaginal delivery, 8 (16%) had an instrumental delivery and 17 (34%) had a caesarean section. Half of the women were multiparous and five (20%) had PPH in their previous pregnancy. Nineteen (38%) and 12 (24%) reported at least one significant personal and family bleeding history, respectively. One (2%) woman was identified to have von Willebrand disease. In conclusion, primary PPH does not appear to be a strong predictor of inherited bleeding disorders. Further studies are required to assess the prevalence of inherited bleeding disorders among these women.

Pregnancy in women with congenital factor VII deficiency

The aim was to review the pregnancy and obstetric outcome in women with factor VII (FVII) deficiency. The study group contained women with FVII deficiency, registered with Haemophilia centre and Haemostasis Unit at the Royal Free Hospital, London. The women were interviewed and case notes were reviewed. The main outcome measures were changes in FVII levels in pregnancy, maternal and perinatal outcome. The FVII levels ranged from 7-36 IU dL(-1) in the 13 women included in the study. There were a total of 14 pregnancies in seven women. Ten pregnancies in four women were prior to the diagnosis of FVII deficiency. Following the diagnosis of FVII deficiency, there were four pregnancies in three women. There was an increase in the FVII level during pregnancy in these women from a mean baseline level of 33 IU dL(-1) to a mean of 73 IU dL(-1). These women received recombinant FVIIa replacement during labour and delivery. There were two early pregnancy losses, both associated with excessive haemorrhage. There was only one postpartum haemorrhage in the study. There is a significant increase in FVII levels in pregnancy in women with heterozygous FVII deficiency. The risk of bleeding in early pregnancy might be higher than that at term, due to inadequate rise in the FVII level in early pregnancy.

Topical use of tranexamic acid to control perioperative local bleeding in gynaecology patients with clotting disorders: two cases

Operating on patients with abnormal coagulation is a challenge frequently faced by surgeons. Achieving haemostasis perioperatively can involve bleeding points that would not ordinarily present a problem with intact clotting function. Here we present two women with localised wound bleeding following a gynaecological surgery in the presence of a clotting disorder. Haemostasis was successfully achieved with tropical use of tranexamic acid. These two cases illustrate a novel use for this antifibrinolytic agent. We suggest that there is a role for topical use of tranexamic acid in perioperative haemostasis in patients with clotting disorders.

Factor VIIa in puerperal hemorrhage with disseminated intravascular coagulation

BACKGROUND

[corrected] Puerperal hemorrhage associated with disseminated intravascular coagulation is a life-threatening obstetric emergency. Recombinant factor VIIa is a novel hemostatic agent, but more information concerning its dosage, efficacy, and safety is required.

CASE

A primigravida developed preeclampsia complicated by disseminated intravascular coagulation and severe puerperal hemorrhage after an emergency cesarean at 35(+5) weeks of gestation. Two doses of recombinant factor VIIa controlled the hemorrhage without any thrombotic complications.

CONCLUSION

Recombinant factor VIIa should be considered when conventional methods fail to control puerperal hemorrhage complicated by disseminated intravascular coagulation. A review of 17 similar cases treated with this hemostatic agent revealed that in 76% a single dose ranging from 16.7 to 120 microg/kg controlled bleeding. Guidelines are needed to help obstetricians use recombinant factor VIIa effectively in such emergencies.

Women and von Willebrand Disease: Controversies in Diagnosis and Management

von Willebrand disease (vWD) is the commonest bleeding disorder in women. More than 70% of women with vWD suffer from menorrhagia and half of them suffer from dysmenorrhea. There is also the risk of hemorrhage with ovulation and mid-cycle pain. These have a significant effect on all aspects of quality of life. vWD also can be the underlying cause of menorrhagia in a small but significant proportion of women. There are still several unanswered issues in the diagnosis and management of menorrhagia in these women. There is no consensus whether testing for vWD should be part of the routine investigations in menorrhagia. Diagnosis of vWD is difficult. There are intraindividual variations in von Willebrand factor and factor VIII levels influenced by age, race, and blood group. This is further complicated in women because of the fluctuation of these factor levels during the menstrual cycle and possibly with hormonal therapy. The diagnosis of menorrhagia is also difficult due to the lack of a simple objective tool for the assessment of menstrual blood loss. In vWD, the treatment of menorrhagia is usually medical, but there is lack of prospective data on the efficacy of commonly used medical therapies in these women. The levonorgestrel intrauterine system, Mirena, is effective and should be considered prior to surgical management. Surgical interventions may be required in patients unresponsive to medical treatments. These procedures can be complicated by hemorrhage in these women. A multidisciplinary approach in the management of these women is essential in ensuring an optimal outcome. Multicenter clinical trials are required to answer the controversial issues in the management of women with vWD.

Is inferior dissection of the rectus sheath necessary during Pfannenstiel incision for lower segment Caesarean section? A randomised controlled trial

OBJECTIVE

The objective was to determine the benefit of non-dissection of the rectus sheath inferiorly in a Pfannenstiel incision during an elective Caesarean section with regard to operative blood loss and post-operative pain.

DESIGN

A randomised controlled trial.

SETTING

The Royal Free Teaching Hospital in London.

POPULATION

One hundred and twenty women who underwent elective Caesarean section delivery.

METHOD

Women were randomised to have dissection or non-dissection of the rectus sheath inferiorly during an elective Caesarean section.

MAIN OUTCOME MEASURES

Estimated blood loss during the operation, as well as the difference between pre- and post-operative haemoglobin levels. Post-operative pain was assessed by the visual analogue scale, a verbal rating scale and the use of post-operative analgesia. Patient satisfaction was assessed by a verbal rating scale.

RESULTS

There was no significant difference in the estimated blood loss during the procedure between the two groups; however, the mean difference between the pre-operative and post-operative haemoglobin was significantly smaller in the study group (p=0.05). There was a statistically significant difference in both the visual analogue scale (p-value=0.03) and the verbal rating scale scores (p-value=0.02) for pain between the two groups, with lower scores for the study group. There was no overall difference in the verbal rating scale scores for patient satisfaction.

CONCLUSION

Non-dissection of the rectus sheath inferiorly in Pfannenstiel incisions during Caesarean section procedures is associated with a significant reduction in the post-operative pain as well as a smaller drop in post-operative haemoglobin.
